Q: How do you fix a weak AC airflow?

• <div><p>Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.</p></div>

Q: How often should air ducts be cleaned?

• <div><p>You should <a href="https://www.angi.com/articles/how-often-should-you-clean-your-air-ducts.htm">have your air ducts cleaned</a> every <b>three to five years</b>, according to the National Air Duct Cleaners Association (NADCA). Some methods that use brushes and cleaning agents tend to clean more thoroughly, meaning you can have the ductwork cleaned every six to eight years. If you spot warning signs like mold in the HVAC system or your home consistently dusting despite cleaning, you may need to service your air ducts sooner than expected. </p></div>

Q: What happens when a return vent is blocked?

• <div><p>A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home&rsquo;s air. </p></div>
